Trigger Finger

Trigger finger occurs when the tendons in the fingers or thumbs become inflamed and swollen so that they no longer glide easily over the joints but instead lock or catch momentarily when bent. It is common to feel a pop when the tendon slips out of the lock position and straightens.

What are the signs and symptoms of trigger finger?

  • Swelling and inflammation
  • Pain when bending or straightening fingers and thumbs
  • A popping noise or sensation when fingers or thumbs straighten
